' I (Creo-s3) I 2 Claims.

This invention relates to safety-razors, and refers more particularly tomeans for covering the edges of razor blades carriedby the razors.'

This application is a Acontinuation-in-part of my co-pending U. S.patentfapplication Serial Number 421,270, iiled December 2-, 1941, sincematured into Patent No. 2,320,374, dated June 1, 1943, describing asafety razor having two clamping members which are connected with twolevers and which may be moved through the central opening of adouble-edge razor blade by the pressure of clamping means engaging thesetwo levers, whereby the clamping members clamp this blade upon a guard.l

An object of the present invention is to improve the construction ofsafety razors not only of this type, but of many other types as well,through the provision of suitable means for covering the edges of razorblades carried by the razors, thereby protecting from injury the usersof such razors.

Another object is to combine means covering the edges of razor bladeswith meansvarying the type of shave possible with such blades.

A further object is the provision of a safety razor having edge-coveringmeans which serve at the same time lfor facilitating the cleansing ofthe razor. Y

Other objects of the present invention will become apparent in thecourse ,of thefollowing specification. l

In accomplishing the objects of the present invention it was founddesirable'to-provide a safety razor carrying elongated coveringelements,.

which may be pivotally-mounted upon the corresponding edges of theVguard and which x are used to cover the sharp edges of a'razor blademounted upon the razor. These covering elements may have Yexcentricsurfaces extending closer to or further away-.from the `sharp edgesI ofthe blade, dependingupon the position of the covering element. Thevariation will affect the shaving operation, making it possible to havecloser or less close shaves without changing greatly the pressureexerted user.

The cleaning of the razor is facilitated since the turning of a coveringelement will expose those surfaces whichreceive soap and hair particlesduring the shaving.

The invention will appear more clearly from the following detaileddescription, when taken in connection with the accompanying drawingsshowing, by way of examplepreferred embodiments of the inventive idea.

In the drawings:

Figure 1 shows in side elevation a safety razor in its clampingposition;

Figure 2 is a transverse section through the by the hand of the' head ofthe safety razor, in its inoperative position;

Figure 3 is a top view of the safety razor;

Figure 4 is a top view of a razor having differently constructedcovering elements;

Figures 5 and 6 are a section and an end View, respectively, showing thecovering element of Figure 4 in dilerent positions.

The safety razor shown in Figures l., 2 and 3 of the drawings comprisesa handle It which may be hollow and/or filled with a light-weight fluidand which may be provided with a number oi suction cups II (Fig. 1) forattaching the razor to any suitable surface, such as the edges of a bathtub.

The head of the razor includes a U-shaped frame I2 having a transversepiece I3 which is r'mly connected to the handle I0 and two legs or frameposts HI and I5 having convex top surfaces IS and I'l, respectively(Figs. l and 2). The frame postI I 4 is provided with an arcuate slotI8, while a similar slot I 9 is formed in the frame post I5.

A rod 2U extends between the frame posts I4 and I5 and is used as apivot rod for the levers 2| and 22 which actuate the clamping members 23and 24, respectively. Two guide rods 25 and 25 also extend between theposts I4 and I5 and have vtop surfaces which constitute a continuationof the surfaces I6 and I'I of the posts Ill and I5. The lower arcuatesurfaces 21 and 28 of the guide rods 25 and 2'5 constitute guides overwhich the clamping members 23V and 24 slide. lThe guiderods 25 and 7.8are separated from each other by a space zti through which the clampingvmembers 23ar`1d 24 extend.

The lever 2I which is similar in shape to the lever 22, has` adownwardly extending fingerengaged portion 3B, a sleeve 3| mounted onthe rod 2.1i, an intermediate portion 32, a transverse portion extendingthrough the slots I8 and I9,

a similar downwardly extending finger-engaged portion 36 and upper posts31 provided with slots similar to the slots 35.

Arcuate resilient clamps 33 have ends engaging the levers 2 I and 22 andpressing them one against the other, so that the levers 2l and 22 aremaintained by the clamps 33 in the operative position shown in Figure 1.

The lever 2l is connected and. movable along with a frame-like guardportion 4Q. A similar guard portion 4I is connected with the lever 22.

In the clamping position shown in Figure l, the guard portions ll'l and4i form a substantially continuous blade-supporting surface, so that abladef42 may be conveniently clamped between the guard portions 43 and4I, and the clamping members 23 and 24.

A concave elongated nger-protecting element 43 extends along the outeredge of the guard portion 40 and is pivoted at 44 thereon. The member 43hangs downwardly in the inoperative position of the razor shown inFigure 2. However, after the clamps 39 have moved the parts to theoperative clamping position shown in Figure 1, a sharp edge of the blade42 may be conveniently covered by the member 43 which is swung upwardlyabout its pivots 44. The opposite sharp edge of the blade 42 may becovered by a similar linger-protecting element 45 which is pivoted at 46to the outer edge of the guard portion 4|.

The arcuate clamping members 23 and 24 are similar to each other in formand may be resilient either totally or in part. The members 23 and 24which extend through the space 29 between the guides 25 and 26, haveclamping edges 41 and 48, respectively. In the inoperative positionshown in Figure 2, the clamping edges 41 and 48 are situated one next tothe other, so that a blade 42 may be conveniently placed upon theseedges which will extend through the central opening 49 of the blade. Assoon as manual pressure upon the linger-engaging lever portions 30 and36 is released, the pressure of the clamps 39 will move the levers 2|and 22 toward each other. The clamping member 23 is connected with thelever 2| by pins 50 which are integral with the member 23 and whichextend through slots 35 provided in the posts 34 of the lever 2|. Pinswhich are integral with the clamping member 24, extend through similarslots provided in the posts 31 of the lever` 22. Thus a movement of thelevers 2| and 22 toward each other will swing the clamping members 23and 24 about the guides 25 and 26 and will move them through the centralopening 49 of the blade 42 until the edges 41 and 48 of the clampingmembers will engage the blade 42 and press it firmly against the guardportions 40 and 4|, thereby clamping the blade.

The operation of the razor is apparent from the above description. Theclamps 39 normally hold the parts of the razor in the operative clampingposition shown in Figure 1. In order to move these parts into theinoperative position shown in Figure 2, the user merely presses thengerengaged lever portions 30 and 36 toward each other. The levers 2|and 22 then swing away from each other while being guided in the slotsI8 and I9, and the guard portions 40 and 4| move along with the levers2| and 22. Since the clamping members 23 and 24 are connected with thelevers 2| and 22 by the pins 50 and 5|, the

levers will cause the clamping members to swing about the guides 25 and26 and to withdraw through the central opening 49 of the blade 42 andthe space 29 into the interior of the frame 2 until the clamping membersreach the position shown in Figure 2.

Then the used razor blade may be conveniently removed and replaced by anew one.

As soon as manual pressure upon the lever portions 30 and 36 isreleased, the clamps 39 will move the razor parts back to the clampingposition shown in Figure 1.

Figures 4 to 6 show a concave elongated ringerproteoting element 60which extends along the outer edge of a guard 6| of a razor. The element60 has a curved spade-like portion 62 and a round tube-like portion 63which is eccentrically mounted upon a pivot or rod 64. The portion 62may be extended beyond the razor to facilitate the manipulation of theelement 60. The pivot 64 extends through supporting portions 65 and 66of the guard 6| and has a head 61 engaging the supporting portion 65.The opposite end of the pivot 64 is threaded and carries a nut 68, sothat the pivot is held in place.

The portion 63 of the element 60 ts between the guard portions 65 and 66and has outer surfaces 69 which approach or recede from the edge portion10 of a razor blade 1| which is pressed -by a clamp 12 against the guard6|.

Figure 5 shows the element 60 in its completely Withdrawn position, inwhich a space 13 is provided between the cutting edge 10 of the bladeand a surface 14 of .the element 60. It is apparent that soap and hairparticles are deposited upon the surface 14 during the shaving.

In the position shown in Figure 6, the surfaces 69 have been movedtoward the edge 10, thereby closing the space between the cutting edge10 and the element 60. Thus the angle at which the razor meets the skinof the shaver is changed. It is apparent that a closer shave is attainedwhen the element 60 is in the position shown in Figure 5 than when it isin the position shown in Figure 6, if manual pressure remains about thesame.

The element 60 is swung upwardly after the shaving until it is preventedfrom further movement in that direction by the engagement of the outersurfaces 6.9 with the adjacent edge of the guard 6|. At that time, thesurfaces 14 which receive soap and hair particles during the shaving,are so exposed that they vcan be conveniently wiped to remove the soapand hair particles. In its upward position, the element 60 serves as anadequate protector of the cutting edge 10 to preserve the sharpness ofthat edge 10 and to prevent injury to any person grasping the razor.

It is apparent that the speciiic illustrations shown above have beenIgiven by way of illustration and not by way of limitation, and that thestructures above described are subject to wide variation andmodification without departing from the scope or intent of theinvention. All of such variations and modifications are to be includedWithin the scope of the present invention. l y
